Engine Cooling problem
2002 Kia Sedona 6 cyl Front Wheel Drive Automatic 177, 00 miles

Had overheating issue with van 3 months ago and blew heater hose - had it and thermostat replaced. Just began overheating again - used the old heater trick to dissapate engine heat and it worked. Two days ago, after 30 mile drive, overheated almost to max - liquid overflowing from cooling resivour. Let it cool and tried again - soon overheated again with cool air blowing from heater. Took to shop - they let it idle 30 minutes at a time and couldn't make it overheat, yet cool air still blowing from heater. Note: coolant liquid levels had been running low and would have to be topped off about once a week.

With all of this in mind, does this sound like a water pump issue? Is there any way to check to be sure? The shop mechanics finally got it to overheat on a drive - they're not sure it's the water pump because they seem to think there would be a broken belt associated with it, but truth is, they're not sure why it's overheating.

Do you
have the same problem?

Cooling fans coming on? No airlock in the system-could be the water pump. If it continues get it block and pressure tested.

One way to test for a bad water pump is to squeeze the upper radiator hose when the engine is hot and idling. Careful, because the hose will be HOT! If you do not feel much coolant circulating through the hose when you rev the engine, the pump may be bad. The other cause might be a bad thermostat that is not opening properly (remove and inspect the thermostat), or a clogged radiator.
